How Is the ‘Security Budget’ of a Blockchain Defined?

The security budget of a blockchain is the total economic value the network spends to secure its ledger. It is primarily defined by the total block rewards (newly minted coins and transaction fees) paid to miners or validators.

A higher security budget means a higher cost for an attacker to compromise the network, as they must outspend the rewards to maintain a malicious chain.
